1. Being controlled by two sets of inverters and PLC industrial control module, applying constant tension control principle, the moving speed of the machine can be adjusted automatically according to the changes of the cutting force to make sure the diamond wire saw be in the best cutting condition all the time.

2. The machine is without phase request. It does notneed to change or distinguish the power phase. The machine has the following production functions: wire broken production, over-loading production, open-phase production, terminal limit, and so on.

3. The lateral moving and the rotation angle of the cutting head are controlled and driven by electric motor. There is photoelectric proximity switch installed on the cutting head for position limitation production. This function enables the machine to work normally under harsh circumstance with moisture and dust.

4. The real-time parameters are displayed on the touch screen of the control platform, such as the set current of the main motor, cutting current, linear speed, walking speed, running time, revolving speed, etc. It makes the operation and adjustment more convenient.

5. The machine can be operated manually and automatically. The manual and automatic functions can be shifted from each other. Under the automatic function, the machine can be unattended operated, and one worker is able to operate multiple machines.

Wirecutter of last generation, it can be considered as a landmark in its field. It can be used on all the types of marble, granite and stone, with top performance and life of the diamond wire, at maximum cutting speed. The whole controls are fully automatic and don't require the constant presence of the operator.Technical features:

Diamond wire running system by electric motor

The electronic system of feed control is extremely accurate and complete, thanking to the combined action of two motors:

• 2 HP motor for the quick positioning of the machine on the rail.

• 0.5 Hp motor with automatic reduction gear for fine regulations.

The feeding on the rail is performed on a double central self-cleaning rack with double gear wheel. This system allows the machine to work even in slope position, preventing the risk of sliding. The " S 1000" is featured by a special "electro-hydraulic" system for flywheel positioning. The rotation and a lateral movement of 40 cm per side are hydraulic, with solenoid valve control. A further lateral movement is possible by electric motor and endless screw. This system allows to perform ground level cuts and two parallel cuts, maximum width 2.0 mt. without moving the machine.

Special feature:

The machine is provided with special blower heating system for flywheel, to reduce icing during winter work.

The diamond wire saw machine had been tested after long time cutting operation in quarry and improved the mechanical & electrical control system, which can achieve automatic moving controlled by constant tension, and infinitely speed adjustment of main flywheel. The working life of diamond wire is highly increased at the same time. Characteristics:

1. Broad applicability: suitable for all kinds of stone quarry.

2. High productivity: Cutting depth can reach 20 meters with fast cutting speed, about 2.5~12 m2/h according to different hardness.

The LGR 1 machine was build for execution of little diamond wire cutting on marble, stones, etc., but also in order to solve problems in building and artistic processing. The effectiveness of LGR 1 machine is confirmed by the extreme ease of working and the processing and cutting speed of the diamond wire. Thanks to this system the operations can be carried out without dust, noise and vibration, being able to perform cutting of any thickness, size and slant on stones like squaring or preparatory bevelled cut of monuments, but also on reinforced concrete, like demolition of base, walls, pillars, stairs, bridges and roads.

The possibility of disassembling the machine into three parts as well as its lightness make the transport easy into small yards and those which are difficult to access. Thanks to its characteristics LGR 1 machine allows to execute operations with diamond wire with the best conditions; in fact it can also carry out several cutting edges with different sloping degrees thanks to a total rotation (360°) of the engine flywheel unit and thanks to the manual slide which allows to obtain a perfect alignment between the machine flywheel and the cutting edge.

The electronic control system allows the best use of the machine and of the diamond tool according to the characteristics of cutting. Lochtmans’ diamond wire cutting machines are equipped with accident prevention system in order to avoid risks for workers who operate or work near the machine, because the breaking of diamond wire can create projection of circuit elements (matchboards, spacers, springs or parts of cable) and the consequent whip action of the cable.

LGR 1 machine is equipped with a very practical and functional protection system. Thanks to the protection racket and to a simple movement, it can be possible to set the fillet protection device in any positions of the flywheel engine. The protection device is extensible and it can reach all the open path of diamond wire, also when the machine is in motion. While the machine is moving the screen belt lets off covering the area where the diamond wire goes open, being an effective element of protection.

This machine combine domestic and overseas advantages to developed. The main motor use transducer control step less speed regulation. Walking also control by transducer speed regulation wide range.and with brake overload protect and have different start moment. Machine low failure rate, stable performance, high efficiency and so on , it is the mine over best quarry equipment .

The start can be either via a star/triangle system or via inverter. The inverter allows to vary and to adjust the diamond wire speed from 0 to 40 m/sec.

The VIP 916, with only one positioning operation, allows to make two parallel cuts with spacing of 1.75 m or 2 m.

The VIP 916 is equipped with a hydraulic unit controlling both the rotation and the lateral movement of the head.

The head rotation is via robust center plate and a hydraulic motor.

The lateral head movement is via two chrome plating supporting stems and one hydraulic cylinder.

The VIP 916 travel movement on the rails is by means of a pinion / rack system. There are two available different options of travel system: the first, called “TC”, consists of a central hung rack fixed on the rails. The second one, called “TI”, features two side racks, carved on the track bars.

Both systems can be supplied with automatic travel speed control either via D.C. motor and electronic card, or via asynchronous motor controlled by inverter.

The VIP 916 power board is installed inside the machine.

If provided, the inverter, equipped with a special ventilation system, is mounted inside the frame case, hence well protected against dust and moisture.

The machine is equipped with a portable, compact and a waterproof control panel, for all the controls and adjustments during the cut.

The double-inverter version, one for the main motor and one for the travel movement on the rails, is equipped with PLC.

This version comes with a portable control panel either electromechanical or touch-screen.

The version with touch-screen and related software allows to interface with the operator, with automatic storage and processing of all the data related to cuts, which are essential for an accurate management of the cutting operation. A remote panel without cable, controlling all the positioning and operational functions of the machine, can be supplied as an option.
